项目进行操作。库开发人员通常会把这些原理图与他们的库打包在一起，以便把它们与 Angular CLI 集成在一起。你也可以创建独立的原理图来操作 Angular 应用中的文件和目录结构，以便为你的开发环境定制它们，并让它们符合你的标准和约束。多个原理图还可以串联起来，通过运行其它原理图来完成复杂的操作。</p><p translation-origin="off">You can create your own schematics to operate on Angular projects. Library developers typically package schematics with their libraries in order to integrate them with the Angular CLI. You can also create stand-alone schematics to manipulate the files and constructs in Angular applications as a way of customizing them for your development environment and making them conform to your standards and constraints. Schematics can be chained, running other schematics to perform complex operations.</p><p translation-result="on">在应用程序中操作代码可能既强大又危险。例如，创建一个已存在的文件会出错，如果出现这种情况，就应该放弃已应用的所有其它更改。 Angular 原理图工具通过创建虚拟文件系统来防止副作用和错误。原理图描述了一个可应用于虚拟文件系统的转换管道。当原理图运行时，转换就会被记录在内存中，只有当这些更改被确认有效时，才会应用到实际的文件系统中。</p><p translation-origin="off">Manipulating the code in an application has the potential to be both very powerful and correspondingly dangerous. For example, creating a file that already exists would be an error, and if it was applied immediately, it would discard all the other changes applied so far. The Angular Schematics tooling guards against side effects and errors by creating a virtual file system. A schematic describes a pipeline of transformations that can be applied to the virtual file system. When a schematic runs, the transformations are recorded in memory, and only applied in the real file system once they're confirmed to be valid.</p><h2 id="schematics-concepts" translation-result="on">原理图的概念<a title="Link to this heading" class="header-link" aria-hidden="true" href="guide/schematics-authoring#schematics-concepts"><i class="material-icons">link</i></a></h2><h2 translation-origin="off" id="schematics-concepts">Schematics concepts<a title="Link to this heading" class="header-link" aria-hidden="true" href="guide/schematics-authoring#schematics-concepts"><i class="material-icons">link</i></a></h2><p translation-result="on">原理图的公共 API 定义了表达其基本概念的类。</p><p translation-origin="off">The public API for schematics defines classes that represent the basic concepts.</p><ul><li><p translation-result="on">虚拟文件系统用 <code>Tree</code>（树）表示。<code>Tree</code> 数据结构包含一个<em>基础状态 base</em>（一组已经存在的文件）和一个 <em>暂存区 staging</em>（需要应用到 base 的更改列表）。在进行修改的过程中，你并没有真正改变它的 base，而是把那些修改添加到了暂存区。</p><p translation-origin="off">The virtual file system is represented by a <code>Tree</code>.
